SLAG-BUGGY-TRAIN COUPLING.

SPECIFICATION forming part of Letters Patent No. 573,724, dated December22, 1896.

Application filed February 21, 1896. Serialllox 580,172. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH L. THOMSON, a citizen of the United States ofAmerica, and a resident of Bayonne, county of Hudson, and State of NewJersey, have invented certain new and useful Improvements in Slag-BuggyTrains and Couplers, of which the following is a specification.

Myinvention relates to an improvement in slag-buggy trains and also to adevice for coupling the slag-buggies which make up the train together insuch a manner that they shall form a train of the character hereinafterindicated.

In ordinary blast-furnace practice the slag as it issues from thefurnace is tapped into conical or hemispherical pots mounted upon a pairof wheels, and, after filling, the pots are wheeled off by the handle.Ordinarily slag-buggies used in practice are so large and clumsy thatthey can only be removed by hand separately. In order to facilitate aneasy and efficient removal of the slag, I employ a buggy of thecharacter hereinafter shown, which is larger than the ordinary buggy. Itis of such size that two or more of the same byco upling orlockingtogether may be formed into a train of buggies, which train may beremoved by a horse or may be attached to a rope connected with aWindlass and dragged off from time to time when full. In order to effectthe coupling or locking of the buggies together, at the same time toprovide an unlocking and the emptying of the same at will, I provide alocking device of the character hereinafter indicated.

The invention will be best understood by reference to the accompanyingsheet of drawings,which is hereby made apart of this specification, inwhich- Figure 1 shows a train of slag-buggies coupled together ashereinafter described; Fig. 2, a rear elevation of a single buggy; Fig.3, a plan view of the same; Fig. 4, a side view of the coupling deviceproper, and Fig. 5 an end view of the same on the lines 5 5 of Fig. at.

Similar letters refer to similar parts throu ghout the several views.

In the drawings, A represents the body or by it is pushed or pulled bythe workman, and

which cross-bar serves also to prevent the handle from being removedfrom the coupling device after coupling.

The body A of each buggy composing the train'is provided at the upperedge opposite to the handle B with a projection or lug P, preferablycast thereon, to which the coupling device is attached and to which isattached a plate M, carrying two vertical lugs N and N. The verticallugs N N are provided with the openings S S, Figs. 4 and 5, which are ofsufficient size to permit the insertion of the bar F, which serves as alock to the coupling device. The bar F is provided at one end with theeyeF, by means of which it may be removed.

To couple the buggies together, the handle of any buggy has simply to bedropped into the opening between the lugs N N until the buggy-handlerests in the position shown in Fig. 1 between the vertical lugs N and N.The pin F is then inserted, and in this way the coupling is locked. Inorder to empty the buggy when it is uncoupled and to prevent it fromtipping over, a leg R with a roller R is provided, attached to the pot Adirectly under the handle 13, and when the buggies are uncoupled thebalance of the pot is such as to cause it to tip downward and rest uponthis leg.

In order to uncouple the train, the workman has simply to take a hookand insert it in the eye F of the pin F and draw or otherwise remove thebar, whereupon the handle may be lifted out of the vertical lugs N and Nand the buggy may be dragged off by the handle and emptied.

I claim as my invention In a slag-buggy, the combination with the edgeof a pot, of a locking device composed of two vertical lugs placed uponthe edge of the pot, between which the handle of another pot havingasuitable cross-bar is inserted, so ence of two witnesses, this 20th dayof Febthat the same may be coupled up in a line ruary, 1896. behind thefirst pot, and a suit-able pin for JOSEPH L THOMSON holding down thehandle with which the cross- 5 bar on the handle of the second potengages. Vitnesses:

In testimony that I claim the foregoing as HENRY H. GRAFF,
